What I want is a slow fan. Current marketing seems to require fast, and even the slowest setting on the regulator is too much for me.

Hi guys,
I am planning to buy a new uv based water purifier as the TDS level in my area is acceptable (around 100). I have zeroed on two choices:
Kent Maxx @ 7000
Aquaguard classic @8500

Please advise and help me in deciding. Any other purifiers may be suggested too.

Thanks.

Are you using a regulator or a dimmer? Asking because a lot of electricians install a dimmer instead of a regulator.

Yes, with the newer fans, electronic regulators just cannot slow down the speed sufficiently.They are good for the upper end of the speed only. I have found that using the older wire wound resistor regulators I am able to control the lower speeds better and in a linear fashion. They may not look as sleek as their electronic counterparts and generate some amount of heat but at least you get proper speed control.

lookout for inverter VRF central AC systems. It has a 4 KW unit (functions below 4 KW at 0.5-1KW most of the times due to inverter compressor and depending upon how many indoor units are working and temp required). You can hook upto 4-6 indoor units at places of your choosing depending upon how you want your airflow.

Dear Friends,

My 4 year old RO water purifier (Eureka Forbes) stopped filtering last week and the service personal told me that filters and pump has to be replaced and the cost of replacement is Rs 8200. If not have to go for 2 year AMC plan for same amount and he will replace under AMC.
Now I am thinking of an RO to replace my existing one. Budget max 12000 Rs. The critieria is
1. Minimum maintenance cost (Filter costs for Eureka Forbes is Rs 4200 and I have already replaced filter twice in last 4 years)
2. High life.

Can somebody suggest something good that suits my criteria?

A good air purifier is supposed to have a multi-layer filter & other mechanisms:
- Electo Static PRE Filter which traps large dust particles
- HEPA filter which traps <0.3 microns or even lesser size particles like virus/bacteria/smoke etc
- CARBON activated filter to trap odour/smoke/other gases
- UV light to kill bacteria/germs

Ionizer is supposed to generate negative ions which gets attracted to positive ions floating in the air - as such these particles become heavy and can no longer keep afloat in air we breathe. Many reputed brands of air conditioners claim to have these.

Ozoniser is another method of releasing ozone O3 which chemically reacts and breaks into Oxygen O2 - however lot of controversy surrounds the harmful effects of ozone and long term effects. Quite a few refrigerator brands claim to have ozonisers in their models for keeping the inside fresh and odourless.

On googling, came across Atlanta Health Care | Health Care-Air Purifier, Delhi, India, Air Purifier, Ionic Air Purifier, Hepa Air Purifier,Honeywell Air Purifier,L G Air Purifier,UV Air Purifier,Hepa filter Air Purifier,Air Purifier Filter,Alen Air Purifier,ION Air Purifier, based in Delhi, who are importing these machines and re-branding them. They claim to have supplied these to lot of hospitals/companies as well. Maybe Delhi bhpians can have a look/demo of the same and confirm if these are snake oils or actually usefull.

HEPA is the only purifier that will work. In order to work it has to be a part of the "Air Conditioning System", that is the air being cleaned has to be in a closed circuit. Which essentially means that your rooms have to be sealed and air only entering/exiting through the system. Periodically the stale air is scrubbed (impurities absorbed) if it is a true closed system, or bled out and fresh air injected after passing through the filters.

This is fine for "clean rooms" and factories but impractical in domestic environment.

Consumer Reports, which I hold in high esteem has time and again proved that it does not work. So, I wouldn't buy that, about Ionizers.

That one looks and feels like a toy fan and I never really used it. It is different from what you have shown. I also found the same on ebay as chinese imports.

The Sharp one at over 10k is definitely pricey for just an ion generator. The Eureka Forbes one, from a very cursory perspective, seems to do more for Rs. 3,990.
